| 2. | There are tradeoffs between these gratings : holographic gratings produce less stray light while ruled gratings are more reflective , resulting in higher sensitivity
这些光栅之间有交替：当常规光栅有更多反射时，全息光栅提供少量杂散光，从而产生更高的灵敏度。 |

体全息存储的首选记录材料是光折变晶体(如fe : linbo _ 3 ) ，但直接存储在晶体中的信息容易受光和热的影响而丢失。 |
| 5. | The formation of holographic gratings accompanied by 532 nm irradiation was studied in detail . it was found that the effect of 532 nm laser to the holographic grating lay in two aspects : the acceleration effect of 532 nm laser to the formation of holographic grating is predominant when the intensity of 532 nm laser is low ; while at relatively high intensities of 532 nm laser , the erasure is the main factor to the holographic grating
论文详细研究了在伴随光532nm照射下全息光栅的形成过程，发现532nm激光对于光栅的形成存在两方面的影响：当532nm激光功率较低时，对于全息光栅的形成起主要作用；当532nm激光功率较高时，对于光栅的擦除作用为主。 |
